Specification of Letters lulg Application filed October 21, .1914.Serial No. SiL'Sl. A

To all whom it may concern:

Beit known that I, J OHN MURRAY, a subject of the King of Great Britainand Ireland, and. a resident of Edinburgh, Scotland, have invented acertain new and4 useful Book-Gluing Machine,.of which the fol lowing isthe specification.

The invention has for its object to provide a simple and effectivemachine for coating the backs of books before they are bound with glueor other VadhesiveVand par ticularly for performing that preliminarylgluing done to secure the backs of the Vsuccessive signatures formingthe book. And it comprises improved mechanism for handling the books,and also improved means for distributing the adhesive.

In order that the invention and the manner of performing the samemay beproperly understood, there are hereunto append'- ed three sheets ofexplanatory drawings in Which- Figure 1 Sheet l is a longitudinalelevationand Fig. 2 Sheet 2 a plan, v'hile Figp?, Sheet 3 is an endelevation and Fig. 4 a similar view, partly in section from theoppositeend of the machine, of an example of a machine made according to theinvention, Fig. 5 being an elevation partly in section, and Fig.'6 anend view -of the gluing roller drawn to an enlarged scale.

As shown in the drawings the machine is built up withv two side frames Acarrying at their one end a table A1 which has a platferm A2 beyond itsouter end upon which the books are assembled. Beyond the platform andnearer the center of the machine, the table A1 is gapped along itscenter. At each side of the gap, rails A3 are provided to support thebooks near their ends. Near the end of the gap in the table A1 a secondset of rails A4 is arranged which dividethe back of the books as it wereinto three' parts. At each side of the table A1 there is provided avertically and longitudinally arranged fiexible ccnveyer band B oflink-belt form faced with rubber or other elastic material. The bands Bengage sprocket wheels B1 varrangedat opposite ends of the machine andcarried on vertical spindles B2 journaled in brackets B3. B4. Thebrackets B3 at the table end of the machine are guided in guides B5 inthe table A1, and are engaged by a right and left hand screwed spindle Cmounted transversely Ythe table. The brackets B4 at the'opposite end ofthe maV` chine are carried by a similar spindle C1 vwhich has on itahandwhee'll C2. The spindles C, C1 carry sprocket wheels yC3interconnected by a sprocket chain Ct. The rear pair of the sprocketspindles B2 wheels D engaged by worms D1 slidably keyed cna transverseshaft D2 and held in Vengagement with thewormwheels by vdesecured'on thelower part r pending lugs D3 of the vbrackets and arranged oney oneither side of the worms D1. The transverse shaft D2 is operated Yby ingD1 from a motor D1.

Beneath the rails A1 is arranged an ad hesive applying rollE. As shownin Figs.

4f` and 5, this roll is made inthree partsV which are so` spaced Vas toleave a circumferential gap between each part. In order that theadhesive be properly distributed, it is .necessary that theYdistributing roll be elastic and at the same time resilient. v.Toattain this, the, roll Eis made of soft vrubber, and is piercedlongitudinally withtwo series of circula-r apertures E2. YEnd disks E*are applied to it -to close up the ends'of the apertures E2.

pass between the parts throughthe circumferential gaps formed in it. Theroll E is carried on a transverse sha-ft F journaled at its ends on theone end vof. a pair of levers F1 pivoted at their centers on brackets F2carried on the side frames A.v The-other ends of the levers F1 areattached to theV upper ends of springs F3, the lower ends of which aresecured to arms F 4 extending out from the brackets F2.- The roll E isserved with adhesive from doctor rolls G. G1 fed from an adhesivesupplying tank G2. The intermediate roll G is carried in'eccentricbushesH- in the brackets F2,"so *that it may be adjusted to bear evenlyon beth the roll E and the doctor roll G1, a handle J secured on atransverse shaft J1'being provided by meansof which the pcsitirn of theadhesive tank G2 may be adiusted through the linkage J2. T he roll E isdriven through a train of gearing K. sprocket wheels K1. and a sprocketchain K2, from the'motor D5.

ln operation, the conveyer bands B are adiusted bv means of the rightand left hand screwed spindles C, C1 until they are such The roll Eis-so positionedv beneath the rails'A4 that the latterV chain andsprocket gearbooks being glued.

The bands seize them andtraverse them along the rails A3 on to the second set of rails A4 andover the adhesive applying roll E. They are finally delivered on to thatpart of the rails A* which extends out rearwardly fromfthe machine tocarry them. The roll E as here-- inbefore described is circumferentiallygapped, so that no adhesive is applied to that part of the books whichtravel along the rails A4. The pressure with which the roll E bears onthe back of the books is adjustable by means of the springs F3, so thatthe adhesive. may be adequately distributed.`
